This article aims to analyze the implementation of teleworking as a security practice to face the crisis resulting from the Covid-19 disease. The present paper provides both theoretical and practical results. From a theoretical standpoint, the Baruch and Nicholson approach is extended with environmental, safety, and legal factors that explain telework. From a practical perspective, a database of companies that have introduced telework as a measure to face coronavirus in a crisis context has been obtained. In short, the Covid-19 crisis demonstrates how teleworking has been used by companies to ensure their employees’ safety and to provide continuity to economic activity. Consequently, safety factors are relevant in the study of teleworking and should be considered in further research.

Sleep disorders are often not regarded as an important health problem, despite their impact on heath. Insomnia is the most frequent sleep disorder in mental health. The aim is to quantify the prevalence of insomnia in a population with schizophrenic disorder and assess its influence on quality of life. This is a descriptive, analytical and cross-sectional study conducted in a sample of 267 schizophrenic patients over 18 years of age using consecutive non-probabilistic sampling. The variables of interest were collected by means of the "Cuestionario Oviedo de Sueño," "Insomnia Severity Index" and EuqoQol-5D. The estimation of insomnia in our schizophrenic population according to the International Classification of Disease (ICD-10) criteria was 23.2%. The likelihood of insomnia when there are problems in the quality of life is significant in all its dimensions: mobility OR: 3.54 (95% CI 1.88– 6.65), self-care OR: 2.69 (95% CI 1.36–5.32), usual activities OR: 3.56 (95% CI 1.97–6.44), pain/discomfort OR: 4.29 (95% CI 2.37–7.74) and anxiety/depression OR: 3.01 (95% CI 1.61–5.65). The prevalence of insomnia fluctuates depending on the diagnostic criteria; however, the schizophrenic population shows high prevalence in some clinical characteristics. People with insomnia have a lower quality of life.

On 11 March 2020 the SARS-CoV−2 virus was officially declared a pandemic and measures were set up in various countries to avoid its spread among the population. This paper aims to analyse the perception of risk of COVID−19 infection in the Spanish population. A cross-sectional, descriptive observational study was conducted with a total of 16,372 Spanish participants. An online survey was used to gather data for 5 consecutive days over the compulsory lockdown period which was established after the state of emergency was declared. There is an association between socio-demographic variables and risk perception, and a very strong relationship between this perception and contact and direct experience with the virus in a family, social or professional setting. We also found that compared to working from home, working outside the home increased the perception of risk of infection and the perception of worsening health. Understanding the public perception of the risk of COVID−19 infection is fundamental for establishing effective prevention measures.

This aim of this paper is to determine the relationship between the consumption of tobacco, cannabis, and alcohol (including drunkenness and binge drinking consumption patterns) in the previous 30 days by Spanish adolescents and the information that is available to adolescents on drug consumption. This cross-sectional study employed data from the Survey on Drug Use in Secondary Education in Spain (ESTUDES 2016), which was conducted on students aged 14 to 18 (n = 35,369). Contingency tables, mean comparison tests, and logistic regression analyses were conducted and prevalence ratios (PR) were obtained. The results show that the probability that an adolescent will smoke tobacco is associated with whether their mother and/or father smoke (PR: 1.30), whether some of their friends smoke (PR: 14.23), whether the majority of their friends smoke (PR: 94.05) and how well informed they perceive themselves to be (PR: 1.30). Cannabis use is mainly associated with whether most of their friends also use cannabis (PR: 93.05) and whether they are sufficiently informed regarding this consumption (PR: 1.59). Alcohol consumption is associated with whether their mothers drink regularly (PR: 1.21), whether most of their friends drink (PR: 37.29), and whether they are well informed (PR: 1.28). Getting drunk and binge drinking are associated with whether their friends have these behaviors (PR: 44.81 and 7.36, respectively) and whether they are sufficiently informed (PR: 1.23 for both behaviors). In conclusion, the consumption of these substances is more frequent among Spanish adolescents who believe that they are better informed and whose friends have similar patterns of consumption.

This paper analyses compulsive Internet use among Spanish adolescents as measured by the Compulsive Internet Use Scale (CIUS) of the ESTUDES 2016 survey (national survey on drug use in secondary schools), which was recently added to the statistical programme of the Spanish National Plan on Drugs. We examined two subsamples of Spanish adolescents (those who suffer from compulsive Internet use and those who do not) while taking into account gender and age. Our general hypothesis was that adolescents who suffer from compulsive Internet use have a greater prevalence of alcohol, tobacco, cannabis, sedative, and new substance consumption as well as a greater prevalence of modes of consumption such as getting drunk, drinking with friends in public places (botellón), and binge drinking. While our results confirm these assumptions, they also suggest that gender and age play an ambivalent role in these associations.
